http://static.tvtropes.org/pmwiki/pub/images/daburu_1563.png

Shotaro Hidari was the protege of the late great HardboiledDetective Soukichi Narumi. Philip is a mysterious boy possessing the True Gaia Memory and gifted with all the world's knowledge inside his head. Together, TheyFightCrime by SharingABody as Double.
----
* AllYourColorsCombined: As its name implies, the Prism Memory enables this.
* AllYourPowersCombined: [[SuperMode CycloneJokerXtreme's]] Prism Bicker combines the power of the [[color:green:Cyclone]], [[color:red:Heat]], [[color:gold:Luna]], and [[color:purple:Joker]] or [[color:gray:Metal]] Memories to deliver a very potent Maximum Drive.
* TheBerserker: [=FangJoker=] was this during its first two uses, due to Philip's difficulty in controlling it.
* BizarreAndImprobableBallistics: The [=LunaTrigger=] form fires bullets that do not just home in on the target, but can also travel in curves as Double wants. It might as well be firing bullet-shaped explosive bees...
* BodyHorror: Most of Double's Joker-Based finishers involve his body ''splitting in two''. '''Vertically'''.
* BrokenRecord: [[spoiler:MAXIMUM DRIVE MAXIMUM DRIVE MAXIMUM DRIVE MAXIMUM DRIVE MAXIMUM DRI-]]
* CallingYourAttacks: All of Double's [[FinishingMove Memory Breaks]], as their two halves must be in sync to use one. Shotaro [[InvokedTrope makes up the names himself]], and Philip indulges him to allow his partner some fun.
** Averted with [=CycloneJokerXtreme=]'s Memory Breaks. At first.
** May be justified, as speaking in unison is a good first step to mental synch.
* CatchPhrase: Shotaro and Philip share not one, not two, but ''three'' of them:
** "We are two detectives in one."
** "We are two Kamen Riders in one."
** "Now, count up your crimes!" [[note]]''"Saa, omae no tsumi wo kazoero!"'' -- note that "sins" is a valid alternate translation of ''tsumi'' instead of crimes[[/note]]
* CoolBike: Double's [=HardBoilder=].
* ElementalPowers: Philip's Gaia Memories allow access to these.
** BlowYouAway: The [[color:green:Cyclone]] Memory.
** PlayingWithFire: The [[color:red:Heat]] Memory.
** {{Lunacy}}: The [[color:gold:Luna]] Memory; WordOfGod gives its power as "Illusions", but it seems that [[GreenLanternRing stretching]] is the primary manifestation of this power. See the main entry for more information.
* EverythingsBetterWithSpinning: Episode 8. It's not called Heaven's Tornado for nothing.
** Also, [=FangJoker=]'s rider kick.
** And [=CycloneMetal's=] FinishingMove.
* ExplosiveOverclocking: Episode 27/28's Twin Maximum Drive. The effects of one person alone trying it makes its usage take on shades of HeroicRROD as well.
* FinishingMove: Several:
** [[color:purple:Joker]] Forms: With the exception of [[color:silver:Fang]][[color:purple:Joker]], forms using the [[color:purple:Joker]] Memory involve Double's [[DetachmentCombat body separating]].
*** [[color:green:Cyclone]][[color:purple:Joker]]: ''Joker Extreme'' [[note]]Double splits in half, then the Joker and Cyclone halves kick the target consecutively.[[/note]]
*** [[color:red:Heat]][[color:purple:Joker]]: ''Joker Grenade'' [[note]]Double splits in half and delivers a jumping, flaming punch with the Heat and Joker halves consecutively.[[/note]]
*** [[color:gold:Luna]][[color:purple:Joker]]: ''Joker Strange'' [[note]]Double splits in half, then the Luna half makes four copies of itself that unleash countless chops on the enemy before the Joker half delivers a powerful karate chop.[[/note]]
*** [[color:silver:Fang]][[color:purple:Joker]]: ''Fang Streiser'' [[note]]Upon activation, the Fang Blade appears on the right ankle. Double leaps into the air and does a HurricaneKick.[[/note]]
** [[color:gray:Metal]] Forms
*** [[color:green:Cyclone]][[color:gray:Metal]]: ''Metal Twister'' [[note]]Spins the Metal Shaft, [[RazorWind releasing powerful winds to strike at close-range]]. Changes to a pincer attack called ''Metal Stag Break'' when the Stag Phone is attached to the Metal Shaft.[[/note]]
*** [[color:red:Heat]][[color:gray:Metal]]: ''Metal Branding'' [[note]]The tips of the Metal Shaft ignite, and Double smashes it into the enemy with an explosion.[[/note]]
*** [[color:gold:Luna]][[color:gray:Metal]]: ''Metal Illusion'' [[note]]Double spins the Metal Shaft around to produce RingsOfDeath that hit the enemy, then they all converge for one last blow.[[/note]]
** [[color:blue:Trigger]] Forms
*** [[color:green:Cyclone]][[color:blue:Trigger]]: ''Trigger Aerobuster'' [[note]]Double fires a series of blasts of pressurized air from the Trigger Magnum. Changes to a powerful condensed shot called ''Trigger Bat Shooting'' when the Bat Shot is attached as a scope to the Trigger Magnum.[[/note]]
*** [[color:red:Heat]][[color:blue:Trigger]]: ''Trigger Explosion'' [[note]]The Trigger Magnum fires a laser beam like flame shot, frying the target. When both Memories are used, it changes to ''[=HeatTrigger=] Supernova'' (with the Double Driver repeatedly spouts "'''MAXIMUM DRIVE'''") which is more powerful but makes Double catch fire, seriously injuring Double's body.[[/note]]
*** [[color:gold:Luna]][[color:blue:Trigger]]: ''Trigger Full Burst'' [[note]][[BeamSpam A massive barrage of homing shots from the Trigger Magnum]]. Changes to a double pincer ray called ''Trigger Stag Burst'' when the Stag Phone Memory Gadget is attached to the gun.[[/note]]
** [[color:green:Cyclone]][[color:purple:Joker]][[color:silver:Xtreme]]: This form has a total of five finishing moves.
*** ''Double Xtreme'': A tornado, larger than the one used by [[color:green:Cyclone]][[color:purple:Joker]], lifts Double into the sky and speeds them towards the foe.
*** ''Prism Break'': A slash from the Prism Sword.
*** ''Bicker Charge Break'': A slash from the Prism Sword after being charged up by the Bicker Shield using the [[color:green:Cyclone]], [[color:red:Heat]], [[color:gold:Luna]], and [[color:purple:Joker]] Memories.
*** ''Bicker Finallusion'': A laser blast from the Prism Bicker with the [[color:green:Cyclone]], [[color:red:Heat]], [[color:gold:Luna]], and [[color:purple:Joker]] Memories. A variation with the [[color:gray:Metal]] Memory replacing the Joker Memory creates a laser shield that protects against powerful attacks.
*** ''Double Prism Xtreme'': A Twin Maximum Drive with the Prism Memory in the Maximum Slot; a bicycle kick.
** [[color:green:Cyclone]][[color:purple:Joker]][[color:gold:Gold]][[color:silver:Xtreme]]: ''Golden Xtreme'' [[note]]An enhanced version of the ''Double Xtreme''.[[/note]]
** A couple of other Maximum Drives without names have been performed with the Memory Gadgets.
*** [[color:maroon:Stag]] Phone with [[color:red:Heat]] Memory: Engulfs the Stag Phone in fire.
*** [[color:navy:Bat]] Shot with [[color:gold:Luna]] Memory: Sets off a series of flash bulb bursts that disorient the target.
* FusionDance: It's not really two people fusing into one, but more like the soul of one person goes into the other's body. So there's a limp body that needs protecting.
** Played straight when Double's [[color:green:Cyclone]][[color:purple:Joker]][[color:silver:Xtreme]] form fuses both Shotaro's and Philip's bodies together.
* GivingSomeoneThePointerFinger: Before the beatdown.
* {{The Hero}}(es)
* IncendiaryExponent: The [[color:red:Heat]] Memory can ignite [=HeatJoker's=] right fist or the [[color:gray:Metal Shaft]] as [=HeatMetal=] for the Memory Break.
* MidSeasonUpgrade: [[color:silver:Fang]][[color:purple:Joker]]
* MultiformBalance
** Shotaro:
*** JackOfAllStats: Joker
*** StoneWall: Metal
*** GlassCannon: Trigger
** Phillip:
*** FragileSpeedster: Cyclone
*** MightyGlacier: Heat
*** SquishyWizard: Luna
** Special Combinations:
*** LightningBruiser: [=FangJoker=]
*** SuperMode: [=CycloneJokerXtreme=]
*** SerialEscalation: [=CycloneJokerGoldXtreme=]
* PowerGivesYouWings: [[color:green:Cyclone]][[color:purple:Joker]][[color:gold:Gold]][[color:silver:Xtreme]] from TheMovie, [[MythologyGag which bears a resemblance to]] [[Series/KamenRiderBlade Blade's Jack Form]].
* RazorWind: [[color:green:Cyclone]][[color:gray:Metal]] can execute these with the [[color:gray:Metal Shaft]] even without using a Memory Break.
* RubberMan: [[color:gold:Luna]][[color:purple:Joker]] can stretch his right limbs.
* SpotlightStealingSquad: The [[color:red:Heat]] Memory is probably the most used memory of all, not just within the three (four if you count [[color:silver:Fang]]) Philip uses.
** In a similar vein, Shotaro prefers the [[color:purple:Joker]] Memory the most.
* ThemeMusicPowerUp: Every time Double transforms.
* WeaponOfChoice: Either Shotaro's Gaia Memories or a special Gaia Memory allow access to these.
** Shotaro:
*** BareFistedMonk: The [[color:purple:Joker]] Memory, which allows Double to perform Rider Kicks/Rider Punches/Rider Chops.
*** SimpleStaff: The [[color:gray:Metal]] Memory with the Metal Shaft. Turns into a [[WhipItGood whip]] with the [[color:gold:Luna]] Memory on the right side.
*** {{Handguns}}: The [[color:blue:Trigger]] Memory with the Trigger Magnum.
** Special Combinations:
*** SpikesOfDoom: The Fang Memory, which allows Double to manifest a bladed weapon on his body.
*** BifurcatedWeapon: The Xtreme Memory with the Prism Bicker, which can split into the [[CoolSword Prism Sword]] and [[LuckilyMyShieldWillProtectMe Bicker Shield]].

!!!Shotaro Hidari/Kamen Rider Joker
!!!Portrayed by: Renn Kiriyama (live), Seiji Takaiwa (suit)
[[quoteright:168:http://static.tvtropes.org/pmwiki/pub/images/shotarokun_7617.png]]

Shotaro was the protege of the private detective Soukichi Narumi. Upon the events of Begins Night he takes up on his mentor's mantle, solving Dopant cases. His Gaia Memories, featured on the left side of Double, grant Double a weapon or a fighting style. In the second movie, he takes on the mantle of Kamen Rider Joker after Philip is kidnapped, using a Lost Driver and the Joker Memory to transform. [[spoiler:He resumes the mantle of Kamen Rider Joker in the series finale upon Philip's disappearance.]]
----
* ArcWords: "[[HardboiledDetective Hard-boiled]]", what with him being a private detective and all. It makes its way into his bike, the Machine [=HardBoilder=].
* BadassNormal: Aside from having the Double Driver and training in detective work, Shotaro is more or less a normal human being when not Double. [[spoiler:Which is why he can be affected in all manner of negative ways by the attacks of some Dopants such as Old and Terror, which both Philip and Terui can shrug off due to their "unique physiologies", as Shroud puts it.]]
** Arguably carries over into his transformation as Kamen Rider Joker. Not only does he have no special powers or weapons outside of enhanced strength, [[AllThereInTheManual supplementary materials]] show that stats-wise it is in every way weaker than [[JackOfAllStats CycloneJoker]].
* BareFistedMonk: When using the Joker Memory in the Lost Driver to become Kamen Rider Joker.
* BelligerentSexualTension: Arguably, with Akiko.
* BerserkButton: Don't you dare make anyone cry in his presence.
** In particular, the sight of someone crying has lead him to threaten Nasca to never make the children of the city cry and also to attempt [[spoiler:a [[strike: potentially lethal]] ''suicidal'' [[DangerousForbiddenTechnique Twin Maximum Drive]]]] when Ryu breaks down in tears after [[spoiler:Isaka gives him TheReasonYouSuckSpeech about why he is too weak and pathetic to ever defeat the Weather Dopant]].
* BettyAndVeronica: The Betty to Ryu's Veronica for Akiko's Archie. He loses.
* CannotSpitItOut: He can't bring himself to tell Akiko about her father's death, nor can he tell a little girl [[spoiler:her father is in fact dead and not Double]]. TheMovie has Akiko finding out anyway, but she still wants Shotaro to openly say it to her.
** In the Director's Cut of the film, there's a new scene where Shotaro promises to sit down with Akiko and tell her everything about her father after they resolve the issue with the D[[spoiler:ummy]] Dopant.
* CantCatchUp: Shotaro gets this after [[spoiler:Philip's power boost from the Xtreme Memory. He does manage to get better, unlocking their SuperMode in the process]].
* CartwrightCurse: A non-lethal variation, but every single time he shows interest in a woman, she's either the MonsterOfTheWeek or simply doesn't notice.
* ChivalrousPervert: He's going to do ''nearly anything'' for a lady he fancies. Taken to its logical conclusion during the Invisible Dopant arc, wherein Lily Shirogane lands on Shotaro in an, er, compromising pose.
* DarkAndTroubledPast: Somewhat implied in the Jewel Dopant arc, where his flashbacks show him repeatedly running away from Jinno back when the latter was a beat cop.
* FinishingMove: As Kamen Rider Joker, Shotaro has two, arguably homages to Series/KamenRiderBlack:
** Joker 1: ''Rider Kick'' [[note]]Joker jumps and kicks the Dopant.[[/note]]
** Joker 2: ''Rider Punch'' [[note]]Joker delivers a powerful punch.[[/note]]
* TheHeart: It's his good heart that makes Philip ultimately reaffirm their partnership, [[spoiler:even after the events of the Beast arc]]. He also manages to transform Ryu Terui from a rage-powered man who hates Futo to a warrior on the side of love.
* HeterosexualLifePartners: With Phillip, at least by the end. They even call each other 'partner'.
* {{Homage}}: Kamen Rider Joker from TheMovie is one to Series/KamenRiderBlack, arguably.
* IDoNotLikeGreenEggsAndHam: Shotaro's reaction to the JidaiGeki ShowWithinAShow ''Kaze no Saheiji, Panic Revenger''.
* TheKirk
* LargeHam: Look at his facial expressions. ''Look at them.''
* MasterOfNone: As Kamen Rider Joker.
* MeaningfulName: His surname literally means "left".
* MyGreatestFailure: Sokichi's death, which Shotaro thinks is his fault because he went against direct orders from the boss. Addressed quite directly when the dying Sokichi [[TakeUpMySword passing on his cool hat]]; Shotaro says he's not ready for it, to which Sokichi responds "Then become a man worthy of wearing it."
** [[spoiler:In the penultimate episode, Shotaro pulls the hat off the wall and wears it when he confronts Kazu, showing that he's finally gotten past the guilt.]]
* NiceHat: A fedora.
** FedoraOfAsskicking
* PrivateDetective: Almost the HardboiledDetective variety.
* PrivateEyeMonologue: He has a penchant for these and usually ends up saying them out loud when he shouldn't. Every arc usually ends with one.
* RunningGag: His "Half-boiled" lifestyle, used to mock his self-proclaimed [[HardboiledDetective hard-boiled]] image.
* SmallNameBigEgo: A mild version; he's somewhat competent, just not as hardboiled as he thinks he is.
* SpannerInTheWorks: Both to [[spoiler:Shroud]]'s plans, initially and later to Ryubee's. Ironically [[spoiler:Shroud]] would end up relying on Shotaro being this to Ryubee, calling him a WildCard. Then, he {{lampshades}} this against Foundation X:
-->'''Shotaro''': "I'm here to screw up your plan."
** It's not all good though. This trope does take a dark take when he [[spoiler:screws up his mentor's plan through rescuing Phillip, which eventually cost Narumi his life]].

!!!Philip ([[spoiler:Raito Sonozaki]])
!!!Portrayed by: Masaki Suda
[[quoteright:168:http://static.tvtropes.org/pmwiki/pub/images/philipkun_7998.png]]

Philip is a mysterious boy, possessing the True Gaia Memory. He was rescued by Soukichi Narumi and Shotaro during the events of Begins Night. He aids Shotaro in solving Dopant cases by accessing the Gaia Library, allowing him to look up endless amounts of information. This ability also lends itself to his obsession with research. His Gaia Memories, on Double's right, grant him an elemental power, or in [=FangJoker's=] case, an upgrade. [[spoiler: Is kidnapped in TheMovie for NEVER's plans, yet Shotaro rescues him and the two defeat Kamen Rider Eternal. Later, Philip is revealed to have died twelve years prior to the series, being resurrected as an avatar of the Gaia Memory. Due to this and Ryubee initiating the Gaia Impact, which eventually failed, Philip slowly broke down into data, until a transformation into Double would make him disappear forever. However, Wakana eventually learns the truth, sacrificing her own body to provide a way for Philip to regenerate in the recreates Xtreme Memory.]]
----
* ApocalypseMaiden: In TheMovie.
* AttractiveBentGender: See DisguisedInDrag below.
* [[spoiler:BackFromTheDead: In the finale.]]
* BigEater: Philip will do this for the sake of his research.
* CatchPhrase: "Fascinating!" [[note]]"Zokuzoku suru ne!"[[/note]], as well as "Bingo!" as a minor one.
* CuteBookworm: Shy? Not exactly. Vulnerable? Depends. Cute and brainy? Definitely. Also [[IncrediblyLamePun doubles]] as BadassBookworm.
* [[spoiler:DeadAllAlong]]
* DeadlyUpgrade: [=FangJoker=] set Philip's mind on fire at first, despite it taking the protagonists two minutes after its television debut to get proper control over it.
* {{Deuteragonist}}
* [[spoiler:DisappearsIntoLight: Well, into data, but still.]]
* DisguisedInDrag: Except for his voice, he makes for a ''very convincing'' Wakana. Well, his clothing ''is'' marketed towards women...
** [[spoiler:Well, there's also the fact that Philip and Wakana are siblings - the family resemblance would be sufficient.]]
* DudeLooksLikeALady
* EverythingsBetterWithDinosaurs: The [[color:silver:Fang]] Memory, made to protect him, has a Velociraptor-like Live Mode, and allows access to the spiny [=FangJoker=] form.
** Fang also takes the shape of a dinosaur head when connected to the Double Driver.
* TheExoticDetective
* ExtremeOmnivore: Philip develops a taste for... vinegar, after Akiko used it a couple of times on him as an all-purpose elixir.
* GoGoEnslavement: In ''Forever A to Z'', when Phillip got captured by NEVER, they dressed him up in one of their uniforms.
* HairDecorations: Freakin' ''binder clips''.
* HeterosexualLifePartners: With Shotaro, at least by the end. They even call each other "partner" [[note]]"Aibou", a word also often used in ''Series/EngineSentaiGoOnger''[[/note]].
* [[spoiler:HeroicRROD: His body starts to disintegrate after the initial plan for Gaia Impact is ruined.]]
* ImmortalityBeginsAtTwenty: Delusion Diary #11 hints that Philip will forever remain seventeen years old because [[spoiler: he's composed of the Earth's data.]]
* ImprobableHairstyle: Very noticeble in episode 16. His hair looks messy after taking off his motorcycle helmet, but in the next shot it's as perfect as always.
* InstantExpert: Every now and then the data Phillip searches for will stick in his head for a while.
* KnowledgeBroker
* MeaningfulName: [[spoiler:His real name is ''Raito'' Sonozaki, and he's the right side of ''Double'']]. His name also references Literature/PhilipMarlowe.
* MysteriousWaif
* OfCorpseHesAlive: Whenever his mind is in Double's body, Philip is unconscious, so his lifeless body is a sitting duck. In episode 7, nobody tried to interact with them, but Akiko had to make-believe they were napping sweethearts, so as not to draw attention on the bus.
* [[spoiler:PhlebotinumBreakdown: After the failed Gaia Impact, Philip's body is returning to data, hastened by transformation.]]
* ScarfOfAsskicking: The [[color:green:Cyclone]] Memory comes with the iconic scarf. Double's scarf is known as the Windy Stabilizer.
* SkilledButNaive
* TheSmartGuy
* SpellMyNameWithAnS: His name is spelt as "Philippe" in the aura that surrounds his body when he enters the Gaia Library, but now Toei seems to have gone with Philip.
* TheSpock
* [[spoiler:TomatoInTheMirror: Episode 38. That is all.]]
* [[spoiler:TouchedByVorlons: His encounter with the Xtreme Memory gave him a huge power boost that Shotaro can't keep up with. Not to mention that he died as a child and the "green light" of the True Gaia Memory revived him, along with the ability to access the Gaia Library.]]
* TheWatson
* [[spoiler:WhiteSheep]]
* WikiWalk

!!Akiko Narumi/Terui | [-Actor: Hikaru Yamamoto-]

Akiko is the Boss's daughter, coming in to replace her father. As Shotaro's landlady she proclaims herself as the Chief of the Narumi Detective Agency, specializing in Dopant cases.

* ArmedLegs: Played for laughs with her slipper.
* BelligerentSexualTension: With Shotaro, arguably.
* BerserkButton: Akiko will cop to the beautiful part, but she's no middle-schooler!
* BettyAndVeronica: The Archie for Shotaro's Betty and Ryu's Veronica. She chooses Ryu.
* BigEater: Can wolf down enormous quantities of sweets
* BigNo: After giving word of her treat to two men [[BigEater whose appetite she knows nothing about]].
* CatchPhrase: "No one told me about this~!" [[note]]''Atashi kiitenai~!''[[/note]]
* CrouchingMoronHiddenBadass: She as actually quite the competent detective, when the chips are down.
* [[spoiler:DidYouJustFlipOffCthulhu: Slipper-slaps ''Clay Doll'' Dopant, just after the latter's upgrade process.]]
* HappilyMarried: [[spoiler:Subverted for a while in Accel's V Cinema. She got better afterwards.]]
* IconicItem: Her slipper, of course.
* TheIdiotFromOsaka: Has shades of this, given her quite black and white view of the world, but she does keep Shotaro focused on the case.
* KansaiRegionalAccent: Akiko refers to herself using the ''uchi-'' pronoun. It does help that her actress Hikaru Yamamoto is from Osaka just like her character.
* {{Kawaiiko}}
* LargeHam
* ManicPixieDreamGirl: One that Shotaro doesn't want in his life.
* TheMcCoy
* TheNapoleon: Don't call her a middle-schooler (but she'll gladly be called beautiful).
* WhenYouComingHomeDad: Her relationship with her father was like this when she was a child, with Akiko becoming upset that he was too busy to visit her, including on her birthday (though she wasn't aware at the time that he was a Kamen Rider.)
* OfficialCouple: With Ryu
* ShoeSlap: Akiko's [[PaperFanOfDoom slipper-slap]] acts as a DopeSlap (on Shotaro [[labelnote:*]]not that he's an idiot... he just [[LargeHam tends]] to [[PrivateEyeMonologue sidetrack]].[[/labelnote]]), as a GetAHoldOfYourselfMan (on Philip in episode 4), then finally gets played straight (used on [[spoiler:Wakana as Claydoll Dopant]]).
** In Ep. 14, Shotaro gets payback by hitting her with her own slipper.
** In a more meta example, she combines the slipper slap with PercussiveMaintenance in the [[http://www.youtube.com/watch?v=HsLvr_jo-Zk&fmt=18 music video]] for the opening theme song. The results are bizarre, to say the least.
** Durning her dream in the Nightmare arc, her slipper serves as [[color:green:Cyclone]][[color:purple:Joker's]] primary weapon, and she beats the crap out of the Nightmare Dopant with it (or tries to, at least).
** And she manages to outdo herself yet again in episode 40 by slapping Wakana in her Claydoll form [[spoiler:who had just received the Gaia Progressor]].
* {{Tsundere}}

!!Sokichi Narumi/Kamen Rider [[color:indigo:Skull]] ([[color:indigo:Crystal]]) | [-Actor: Koji Kikkawa-]

Sokichi Narumi was Shotaro's boss, who taught the young man the trade of a PrivateDetective. During a mission to liberate a young man he dubbed Philip, he was shot at and was killed. The events of ''[[TheMovie Movie Wars 2010]]'' reveal that he was Kamen Rider Skull, while ''Movie Wars CORE'' is a WholeEpisodeFlashback showing him as Skull Crystal ten years before the ''Double'' TV series.

* [[spoiler:TheAtoner]]
-->'''Sokichi''': [[spoiler:First, I wasn't able to reveal the darkness within a friend who's always close to me. Second, I hesistated for a while in combat. Third, the city cries because of this.]]
* {{Badass}}: YES!
** BadassBiker: OH YEAH!
* TheCastShowOff: Koji Kikkawa sings his own theme song.
* CoolBike: The [=SkullBoilder=], which is a [[PaintItBlack black version]] of the [=HardBoilder=].
* CoolOldGuy: Well, not THAT old, but you get the point.
* DaddyHadAGoodReasonForAbandoningYou: Well, "[[spoiler: if Daddy ever touches you again you'll explode]]" probably qualifies for a darn good reason.
* DeathByOriginStory
* FinishingMove: ''Skull Punisher'' [[note]]A Rider Shooting attack using the Skull Magnum.[[/note]]
** An unnamed Rider Kick executed with the Skull Memory in the Maximum Slot, which creates an energy skull that Soukichi kicks towards the Dopant[[note]]''Ganbaride'' simply calls this move "Hissatsu Kick", while other sources refer to it as 'Skull Banisher'.[[/note]].
*** Not to mention, the Skull summoned by [[Series/KamenRiderDecade Diend Complete Form]] in ''[[Series/KamenRiderDenO Chou Den-O Trilogy: Episode Yellow]]'' performs a Rider Kick that more closely resembles the Joker Extreme.
* TheGunslinger: Skull Magnum
* ManInWhite
* MentorOccupationalHazard
* NiceHat: A batch of which he apparently passed on to Shotaro.
** FedoraOfAsskicking
* NoOntologicalInertia: Possibly the only aversion in all of tokustatsu; for once defeating the monster does ''not'' remove its curse, [[spoiler:so he can never see his daughter again.]]
* NotSoStoic: [[spoiler:The Chief is revealed to have a half-boiled side in episode 32.]]
* PosthumousCharacter
* SuperPrototype: Skull is the prototype for Double, best illustrated by its being a jack-of-all-trades combination of Shotaro's Memories (melee brawler like Joker, good defense like [[color:silver:Metal]], TheGunslinger like [[color:blue:Trigger]]).
* [[spoiler:TouchOfDeath: Thanks to the Spider Dopant, he can never touch Akiko or she will explode - thus explaining his long absence from his daughter's life.]]

!!Ryu Terui/Kamen Rider Accel
!!!Portrayed by: Minehiro Kinomoto (live), Eitoku (suit)
http://static.tvtropes.org/pmwiki/pub/images/accel_755.png
[[quoteright:168:http://static.tvtropes.org/pmwiki/pub/images/ryukun_7267.png]]

Ryu Terui is a police superintendent assigned to the Futo Police Department's Paranormal Crime Investigation Division, and is thus Jinno and Makura's superior. His family was murdered by a man with a W memory, giving him a motivation to exact revenge. When he meets up with the enigmatic Shroud, she gives him his gear, allowing him to transform into Kamen Rider Accel.
----
* ArchEnemy: Isaka
* BadassBiker: Let's see: his attire completely fitting of a biker (leather jacket and pants, riding gloves and boots), he rides around on a motorcycle that's not a Rider Machine (and a Ducati at that[[note]]the first European bike to feature in a Rider series since the Gas Gas bikes in ''Series/KamenRiderKuuga'', as well as a break in the recent pattern of Riders owning custom-made bikes from Honda[[/note]]), he has a motorcycle {{Motif}} as a Rider, and he can ''become'' a bike while transformed into Accel.
* BerserkButton: He won't listen to reason once the Weather Dopant comes calling. Learning to rein himself in whenever Weather baits him is part of his CharacterDevelopment.
* BettyAndVeronica: The Veronica to Shotaro's Betty for Akiko's Archie. He wins.
* BigBrotherInstinct: Flashbacks showed that Ryu's sister was very important to him, and even was the one who gave him the [[MementoMacGuffin necklace]] he wears in the series. One episode arc has him helping out a victim because she resembled his sister to a T.
* BodyHorror: His Bike Form takes after the Final Form Rides of [[Series/KamenRiderDecade the previous series]], with some subtle but significant differences.
* CatchPhrase: Four of them.
--> "Don't question me." [[note]]"''Ore ni shitsumon wo suru na."/"Don't ask me questions."[[/note]]
--> "Now, let's break away!" [[note]]"''Saa, furikiru ze!''"/"Now, I'll shake you off!"[[/note]]
--> "Despair awaits you at the finish line." [[note]]"''Zetsubo ga omae no goaru da.''"/"Despair is your goal."[[/note]]
--> "It's time for your despair!"
* ChickMagnet
* CoolBike: Ryu's rad red Ducati 999, Diablossa. He also has a Bike Form as Accel, all ConspicuousCG, but also RuleOfCool.
* CoolSword: The Engine Blade.
* DeathByOriginStory: One that mirrors [[Series/KamenRiderV3 V3's]], natch.
* DeathSeeker: Ryu becomes one when he finally tracks down Dr. Isaka. Shotaro [[WhatTheHellHero calls him out on it]], and he eventually gets over it.
* FinishingMove: Several:
** [[color:crimson:Accel]]: ''Accel Glanzer'' [[note]]Kamen Rider Accel uses a flying reverse roundhouse kick that uses the wheel half on his right leg to leave a skid-mark like trail.[[/note]]
** [[color:grey:Engine]]: Four variations:
*** ''Dynamic Ace'': The [=EngineBlade=] blasts a giant letter A out of the blade into the enemy.
*** ''A-Slasher'': Accel uses the [=EngineBlade=] to make three slashes in the shape of the letter A, be it a birds eye view or in front of him, to attack.
*** ''Engine Bike Dasher'': Accel transforms into Bike Form and then [[RammingAlwaysWorks drives straight through the target]].
*** (''Unnamed''): Accel spins around while slashing multiple targets before stopping a moment to spin into the opposite direction (still slashing) and then stops again to finish them off with normal slashes.
** [[color:green:Cyclone]]: Accel performs a wind-powered slash with the [=EngineBlade=].
** [[color:crimson:Accel]][[color:navy:Gunner]]: ''Gunner Full Break'' [[note]]Accel in the [=AccelGunner=] fires a blast from its tank-mounted {{BFG}}, the Gaia Cannon, to defeat a Dopant turned giant.[[/note]]
** [[color:crimson:Accel]][[color:red:Turbuler]]: ''[=AccelTurbuler=] Phoenix'' [[note]]Accel, connected to the Turbuler attachment, bursts into flames and rams through the enemy in midair.[[/note]]
** [[color:blue:Trial]]: ''Machine Gun Spike'' [[note]]Accel Trial delivers multiple kicks that burn a giant letter T onto the enemy.[[/note]]
** [[color:blue:Trial]] / [[color:grey:Engine]]: ''Machine Gun Slasher'' [[note]]Accel Trial delivers a series of rapid slashes with the [=EngineBlade=] to the enemy.[[/note]]
** [[color:crimson:Accel]][[color:gold:Booster]] / [[color:grey:Engine]]: ''Boost Slasher'' [[note]]The Engine Blade turns into a glowing golden energy blade and Accel slashes through the enemy as he flies through.[[/note]]
* FireIceLightning: Accel's Engine Blade has settings for steam, fire, and lightning, representing three types of engines (Steam, Jet, and Electric).
* HappilyMarried
* {{Homage}}: His character design mirrors that of [[Manga/{{Akira}} Kaneda]]. Also, his Rider armor is red and has a monoeye, he holds a high rank despite being young, and is rivals with one who has a W crest... [[Anime/MobileSuitGundam Char Aznable]]?
* ItWasAGift: All of his gear was given to him by Shroud.
* JuggleFu: Part of Machine Gun Spike. He starts the Trial Memory's countdown, throws it ahead of him, runs up to his opponent and kicks them an insane amount of times, then catches the Trial Memory on its way down.
* KirkSummation: To Shroud in episode 45
* LoveRedeems: He believes his love for Akiko helped him overcome his craze for vengeance.
* MeaningfulName: He wears bright red and has fire-themed powers, and his name means 'Dragon Shining-well'.
* MultiformBalance
** Accel: A MightyGlacier thanks to its heavy armor and exceptional attack power.
** Bike Form: A LightningBruiser due to the maximum speed Accel gains as a motorcycle.
** Accel Trial: A FragileSpeedster that loses much of Accel's armor in return for moving at SuperSpeed.
** Accel Booster: The JackOfAllStats thanks to its having more armor than Trial but greater speed than Accel, plus the ability to fly. Also be an EleventhHourSuperpower and possibly not a regular form since [[spoiler:it comes from connecting the Enhancement Adapter to the Accel Memory, which doesn't physically change, and he detransformed into Ryu after finishing off the Commander Dopant]].
* OfficialCouple: With Akiko.
* TheOnlyOneAllowedToDefeatYou: For the Weather Dopant
* OnlySaneMan: Once he [[CharacterDevelopment gets over]] his dream of vengeance, Ryu is probably the most sensible main character compared to [[LargeHam everybody else]].
* PunctuatedForEmphasis: "Hen... '''''SHIN!'''''
* TheRival: Subverted. Ryu was introduced in "The I Doesn't Stop" as a character whose moral stance and personality were fundamentally opposed to Shotaro's, fitting the general pattern of secondary Riders introduced in the Heisei era [[note]]e.g., Kaixa, Leangle, [=TheBee=], IXA, Diend[[/note]]. A rivalry, however, never developed due to both characters being willing to talk things out and genuine CharacterDevelopment on Ryu's part, making Ryu more of a genuine friend to Shotaro than TheRival. Since characters in Heisei Rider shows are usually ''far'' more willing to fight rather than talk things over, this subverts the typical role of the secondary Rider.
* [[SixthRanger Second Rider]]
* SuperMode: [[color:gold:Accel Booster]]
* SuperSpeed: [[color:blue:Accel Trial]]
* TranquilFury: How he ends up [[spoiler:ultimately defeating Isaka]].
* TheWorfEffect: Gets hit with this around episode 45 onward.
** Somehow justified, considering the fact that [[spoiler:he has to deal with TWO absurdly powerful bosses ALONE due to Double's ineffectiveness against Terror, and Shotaro/Philip refuses to henshin against Utopia. They can't guarantee to beat Weather (probably the third most powerful Dopant to date) even when they cooperated, let alone a one-on-one]].
** Also inverted in that when the two worked togather [[spoiler:to divide Terror's efforts, he was able to singlehandedly destroy Terror's Terror Dragon. While still injuried from his previous encounter with it.]]
** Hit with that well before episode 45 as he's usually the guy that gets his butt kicked in order to show how powerful the Dopant of the Week is. Most blatant is the episode right after he gets Accel Trial where he runs into a Dopant that just happens to be even faster than Trial.
*** If you mean [[spoiler:Smilodon Dopant/Mick, it's pretty justified since many episodes earlier (I forgot exactly which) shows it can OUTRUN Luna Trigger's homing bullets. Only Mick and Kirihiko (at Nasca Lv2, which is also where Saeko's Super Speed comes from) can pull off such feat.]]
**** [[spoiler: It is also implied that some of the Smilodon memory's capabilities are strengthened since Mick is a cat. and, to be fair, technically they don't ''defeat'' him.]]
* ZorroMark: Invoked with one Engine Blade FinishingMove, down to the three-cuts gimmick (marking an A instead of Z).

!!Detective Mikio Jinno | [-Actor: Takeshi Nadagi-]

Detective Jinno is a friend of Shotaro's, frequently letting him deal with Dopant cases. He is never seen without his trademark back scratcher.

* ADayInTheLimelight: The Jewel Dopant arc.
* ClearMyName: The subject of episodes 41-42.
* CrouchingMoronHiddenBadass: In Kamen Rider W Returns.
* FriendOnTheForce
* GoodIsDumb: He'll fall for anything (even LookBehindYou), but Shotaro says that it's his strength; Jinno is so earnest that people want to believe he's right, and when he believes that rough characters are actually good deep down, they want to ''be'' good to prove him correct. A prime example of this is Shotaro himself, as shown in flashbacks in the Jewel Dopant arc.
* GratuitousEnglish: Most common user among the cast.
* IconicItem: His back scratcher.
* InspectorLestrade
* SpannerInTheWorks: Doesn't even need to be in the action to fill this role in the Jewel Dopant arc.
* ThoseTwoGuys: With Makura.

!!Detective Shun Makura | [-Actor: Shingo Nakagawa-]

Makura is Detective Jinno's rookie partner, who usually quarrels with Shotaro.

* ButtMonkey
* CowboyCop: Or at least [[SmallNameBigEgo he likes to think he is]].
* IncomingHam: "''Maakurrra [=des'!=]''"; for whenever he follows Jinno (or Ryuu) in introducing himself around the crime scenes.
* LargeHam: If he's on the screen, he's overacting.
* SitcomArchNemesis: With Shotaro, though definitely not a serious case.
* SmallNameBigEgo: ''In spades''.
* ThoseTwoGuys: With Jinno.

* NiceHat: Has a Headpiece of Doom when in his Dopant form. [[spoiler:It can even turn into [[HeadPet a floating monster the size of a house]]!]]
* NightmareFuel: [[invoked]] He produces this as the Terror Dopant. Though he can still produce fear just by staring at someone.
* PapaWolf: Don't you dare hurt Wakana, or you will be in a world of pain.
* SocialDarwinist: His aim is to use the Gaia Memories to weed the weak-minded out of society.
* StealthHiBye: Capable of these ''without involving Gaia Memories.''
* TragicVillain: His FatalFlaw of ambition ultimately costs his family their happiness and unity, as well as [[spoiler:his sanity and, ultimately, his life, as he spends his final moments lauging like a madman in his own burning, crumbling house]]. He'd be a good fit in a Creator/WilliamShakespeare play.
* VillainousBreakdown: [[spoiler:After the Terror Memory is shattered by Double, he ''snaps''. He dies dancing blissfully as the Sonozaki mansion is burning to the ground around him, laughing insanely.]]
* XanatosSpeedChess: Implied between him and Shroud.

Ryubee's elder daughter, assisting her father in the Gaia Memory business. She marries Kirihiko the Gaia Memory salesman. As the Taboo Dopant she can fly and shoot energy. [[spoiler:She turns on him, killing him after he has a HeelFaceTurn. She then got interested in Dr. Shinkuro Isaka, the Weather Dopant, before ''his'' untimely demise. After losing the Taboo Memory to Mick, she recovers the Nasca Memory and uses it, unlocking level 3 until she is defeated by Wakana's Claydoll Xtreme.]]

* BlackWidow: She killed most of her love interests off, [[spoiler:including Kirihiko]].
* {{Chickification}}: She goes through this after [[spoiler:taking up with Isaka]], though it seems like she's doing it on purpose [[spoiler:to make herself seem more attractive]].
* [[spoiler:DiesWideOpen]]
* EnemyMine: Versus [[spoiler:Utopia]].
* EvenEvilHasStandards: Even ''Saeko'' is rather uneasy about [[spoiler:Weather modifying Wakana's Driver to not let her safely transform]].
* EvilGenius: Also a bit of TheDragon, given that she killed off the Boss in the premiere and fights Double at times.
* MeaningfulName: Saeko means cold child, and she spends the series being cold and antagonistic to Wakana.
** Nevermind how it's ''pronounced''... [[note]]probably not intentional, but to the ears of English speakers, "Saeko" sounds like "psycho"[[/note]]
* PaletteSwap: [[spoiler:After losing the Taboo Memory to Mick and having her Gaia Driver destroyed, she starts to use Kirihiko's Nasca Memory, turning into what is currently called "Red Nasca" (it's actually pretty orange).]]
* PyrrhicVictory: [[spoiler:While she manages to survive the downfall of the Museum and Ryubee's death, she loses the Nasca Memory after being defeated by Claydoll Xtreme.]]
* [[spoiler:TheStarscream: For most of the first two acts of the series, it was hinted that she had bigger plans for the Memories beyond those of her father. "Beyond R", the conclusion of the second act, shows her and Isaka first plotting to take Ryubee down and then making their move. Isaka didn't survive, and Saeko went on the lam.]]

!!Wakana Sonozaki/Clay Doll [[spoiler:Xtreme]] Dopant | [-Actor: Rin Asuka-]

The younger daughter of Ryubee, she is a popular idol around Futo, to the point of having her own radio show. Is the least interested in running the family business. As the Clay Doll Dopant she can shoot fireballs from her arm and reform after being broken into pieces. [[spoiler:Her Driver was tampered with by Dr Isaka, which now left her mind open to the madness induced by Gaia Memory usage. Her father also manages to fully turn her to evil just as she plans on escaping Futo with Philip, turning her into the new [[TheDragon Dragon]]. She seemingly dies in the wake of the Sonozaki Mansion's destruction, yet her body was recovered by Jun Kazu to be used in Foundation X's plan.]]

* AstonishinglyAppropriateAppearance: In her first appearance, Wakana wears her hair in a style very similar to her Claydoll Dopant form's head design.

* HeelFaceRevolvingDoor: Following the ''The Radio Q'' arc (Ep. 13&14), Wakana began to regret being involved with the Museum and being the Clay Doll Dopant. Then during the ''The P Game'' arc (Ep. 25&26) she directly attacks her sister due to Isaka's influence. Then in the ''Client X'' arc (Ep. 37&38), she finally is on the cusp of her HeelFaceTurn when ''something'' happens and she becomes completely evil.
* IdolSinger: Gets her own [[{{Defictionalization}} Defictionalized]] single release with "Naturally".
* MagikarpPower: Clay Doll seems to be the weakest of the Gaia Memories used by Museum, primarily useful for its [[GoodThingYouCanHeal regenerative ability.]] [[spoiler: But once she unlocks its Xtreme form, not only is she able to shrug off a Memory Break, her offensive power goes through the roof.]]
* OneWingedAngel[=/=]EvilCounterpart: [[spoiler:The Gaia Progressor she gains from her father grants her Claydoll Xtreme form, which is much more powerful and grants Wakana access to the Gaia Library.]]

[[spoiler:Saeko eventually kills him for attempting to take her with him in a HeelFaceTurn she didn't want.]]

* WellIntentionedExtremist: Loves Fuuto as much as Shotaro does, yet is willing to use Gaia Memories to destroy those who wish it harm.

Shinkuro Isaka is a benefactor of the Sonozaki family and high-ranking member of the Museum. He is the wielder of the Weather Memory, responsible for the murders of Ryu's family.

* {{Fetish}}: Is interested in Saeko's body only when she is in her Dopant form.
* InformedAbility: Supposedly has gained the power of numerous Gaia Memories, yet he always relies only on his ElementalPowers.
* [[spoiler:KarmicDeath]]: {{Lampshaded}} by Shotaro at that.
* [[spoiler:LaserGuidedKarma: When the Weather Memory ''finally'' breaks, Isaka's Living Connectors kill him from the inside out. Guess that's what he gets for dipping into Gaia Memory research a little ''too'' much...]]
* MorallyAmbiguousDoctorate
* PowerBornOfMadness: The reason Isaka doesn't believe in the use of Drivers.
** Incidentally, he's the third strongest Dopant in the series and so completely insane that his own Memory couldn't make him worse.
* SerialKiller: Not only does he murder people to take their Gaia Memories, when he got the Weather Memory, he went on a series of murder sprees simply to test out his various elemental powers. Ryu's family are among his victims.

A representative of Foundation X, which researches Gaia Memories for the Museum. [[spoiler:He rescues Saeko when she is attacked by the Smilodon Dopant and her Taboo Memory is destroyed, and reveals that he wants to help her overthrow Ryubee.]]

* [[spoiler:TheBlank: This is what he does to everyone associated with Philip in order to jumpstart the Gaia Impact.]]

* [[spoiler:LogicalWeakness: Utopia's ability is to drain hope from its opponents and turn it into power, and is shown to be absolutely devastating when used against other living beings. However, this means that the ability is worse than useless against targets that have no concept of hope, such as mechanical automatons and inanimate objects. Shotaro manages to figure this out in time for the final battle, and deploys the memory gadget robots against Utopia to incredible effect, and even blocks the hope-draining ability ''with his hat''.]]
** [[spoiler:This is also a critical factor in Eternal's V Cienma, where he can't draw power from Katsumi Daido/Kamen Rider Eternal (since Katsumi is DeadAllAlong, Kazu obviously cannot draw "hope" from a dead person), allowing Katsumi to completely own him when he became Eternal (and Katsumi actually had a pretty close fight against Kazu even before his henshin).]]

[[folder:Dopants]]

A Dopant is created when a Gaia Memory is inserted into a human body, transforming the user and granting them supernatural powers. Each Gaia Memory contains the culminated knowledge of a single topic extracted from the True Gaia Memory; thus, Gaia Memories can be based on ''anything'' from the history of Earth, from natural phenomena to abstract concepts.

In normal cases, a human requires surgery before they can use a Gaia Memory. A Living Connector is imprinted upon the skin of the user, through which the Gaia Memory can be directly inserted into the body. While this maximises the power of the created Dopant, it carries a significant risk that the Gaia Memory will [[WithGreatPowerComesGreatInsanity consume the sanity of the user]] and create [[ThisIsYourBrainOnEvil a strong addiction to its power]].

Gaia Drivers are external mounts that can be used to insert a Gaia Memory without surgery. While this limits the power of the Memory, it removes the negative side-effects. High-ranking members of the Museum use first-generation Gaia Drivers to transform into Dopants.

Tropes embodied by the Dopants include:

* AnIcePerson: [=IceAge=]
* AttackReflector: Jewel can do it with energy attacks.
* BattleCouple: [[spoiler:Beast and Zone are a husband-and-wife team who robbed an armored car ten years prior to the series.]]
** [[spoiler:Magma and T-Rex]] were a couple who became Dopants together in order to take revenge on their former employer, but then [[spoiler:T-Rex kills Magma when he becomes useless to her because he has been completely taken over by his Memory]].
* BitchInSheepsClothing: The [[spoiler:T-Rex]] dopant [[spoiler: pretended to look sympathetic and drops the act the instant Shotaro found out her true colors.]]
* CardCarryingVillain: Quite a few Dopant abusers come complete with titles like Mr Question and the Radio Clown, sometimes with a one-shot CatchPhrase or BondOneLiner.
* CompellingVoice: Liar, who as the name implies, can literally make anyone believe anything, so long as it's not the absolute truth.
* DangerouslyGenreSavvy: Cockroach, who instead of fighting fairly, uses its SuperSpeed to steal W's Gaia Memories from his belt and runs away with them!
* DisproportionateRetribution: Quite a few Dopants use their powers for really petty reasons.
* DoesThisRemindYouOfAnything: Gaia Memory use is paralleled with drug use.
* ElementalPowers: Magma, [=IceAge=], and Energy
* {{Expy}}: Arguably, Old to Terror, given their "ancient" design and their use of a sort of sludge to attack.
** Also, [=IceAge=] and Triceratops are the first two Dopants Accel faces, compared to Magma and T-Rex, the first two onscreen Dopants Double takes on.
** The Masquerade Dopants could be seen as Expies of the classic Shocker Soldiers, given their skeletal design and status as easily-defeated {{Mooks}}.
* GeneticEngineeringIsTheNewNuke: Gene, for his powers to work, needs biological material but can create ''anything'' from said material. For example, he [[CrowningMomentOfFunny created a plush cow on Shotaro's right hand with two leaves]] during their first fight.
* TheGunslinger: Arms
* {{Invisibility}}: [[CaptainObvious Invisible]], though notably, Lily Shirogane didn't actually ''become'' a monster of any sort; Dr Isaka modified the Invisible Memory to allow her to use its power without such a change.
* ItsPersonal: Many of the Dopants. Notable are [[spoiler:Puppeteer]], who attacks the literary critics that panned the book he wrote in his daughter's memory; [[spoiler:Magma and T-Rex]], who wanted revenge on their old employer for firing them; and [[spoiler:Yesterday]], who turns out to be [[spoiler:Kirihiko's sister]] and wants to get back at Saeko for [[spoiler:her brother's death]].
* KnightTemplar: [[spoiler:Triceratops]] from the series proper. [[spoiler: Commander takes this to ridiculous levels in ''W Returns: Accel'' by murdering ''anyone'' whose commited a crime, even pickpockets.]]
* LegacyCharacter: The final episode of the series establishes that multiples of the same Memories ''do'' exist; in this case, Anomalocaris and Cockroach.
* LoveMakesYouCrazy: Oh ''so much''. [[spoiler:T-Rex]] killed her lover [[spoiler:Magma]] because he went crazy, [[spoiler:Triceratops]] wishes to avenge her lover, [[spoiler:Violence]] is Wakana's StalkerWithACrush, [[spoiler:Nightmare]] is jealous to the point of putting his supposed rivals to sleep, [[spoiler:Jewel]] set his unrequited crush up as the culprit [[spoiler:though he was a monster to begin with]]. [[spoiler:Commander is driven by a desire to avenge his dead wife, but unlike Triceratops, who on her own only wanted to kill those who caused his death, Commander decides to [[KnightTemplar kill all criminals, reguardless of crime]].]]
** The award probably still goes to the [[spoiler:Spider]] Dopant from the Kamen Rider Skull prequel in the "Movie Core War". Unable to live with unrequited love and having a well-hidden, but highly homicidal sense of [[GreenEyedMonster jealousy]], he gained the power to turn people into bombs, set off when a carrier touches someone they love, in a rather horrendous expression of IfICantHaveYou. He ends up detonating a good part of the city in a single go, [[MoralEventHorizon just to prove the lengths he's willing to go to make everyone as miserable as him.]]
* MadeOfDiamond: Jewel, quite literally.
* MagmaMan: [[CaptainObvious Magma, who else?]]
* MoneyFetish: The Money Dopant.
* MonogenderMonsters: Averted; people become Dopants regardless of gender. An even funnier detail to this aversion is that some of the more 'manly' Gaiamemories, like[[spoiler: T-rex and Triceratops]] do in fact have female users.
* MookMaker: The Commander Dopant can create FacelessGoons called Masked Soldiers out of thin air.
* MythologyGag: Hopper is based on a grasshopper and fights with powerful kicks. [[Series/KamenRider Sound]] [[Series/KamenRiderKabuto familiar]]?
** While we're on nods to Kabuto, how about Cockroach (another insect) having SuperSpeed as its main power?
* OneWingedAngel: Certain Memories (particularly the ones based on animals) can make their user a larger Dopant, done in ConspicuousCG.
** Quetzalcoatlus is this right of the bat, with no intermediate humanoid form ever seen (though this might be partly because the "user" was a parrot).
** [[spoiler:Bird]] does this as a result of it's Gaia Memory evolving.
** [[spoiler:Commander upgrades his Gaia Memory to increase his power, changing form in the process.]]
* OvernightAgeUp: Old's specialty, at a price of about 10,000 yen for every year he ages the victim up. (Payment up front.)
* PeoplePuppets: Puppeteer, though he mostly sticks with his dead daughter's CreepyDoll.
* PsychoForHire: Cockroach and Old.
* RightHandOfDoom: Violence, whose left hand is an EpicFlail.
* RoaringRampageOfRevenge: Several are motivated solely by revenge.
* ShockAndAwe: [[spoiler:Energy]] in the finale.
* StockDinosaurs: T-Rex and Triceratops.
* StringyHairedGhostGirl: Virus can come very close, even though she's still alive (though in a coma).
* SuperSpeed: Cockroach, Smilodon, and Donburi.
* SweetTooth: Sweets, who sneaks desserts while working as a maid for the Sonozaki family.
* TeleportSpam: Zone
* TwoGuysAndAGirl: [[spoiler:Jewel and his friends]]. Him finding out that his two friends loved each other didn't go... well with him.
** Which was very similar to Isamu Bitou and [[spoiler:the Beast and Zone Dopants]] (he had no problems with them getting together, [[IWantMyBelovedToBeHappy but still got screwed over for it]]).
* VoluntaryShapeshifting: Other than anyone with a Memory, Dummy can take on the appearance of anyone he wants, usually the dead to take advantage of the dead person's loved ones.
* WellIntentionedExtremist: Triceratops.
** It ''seems'' to be this way with the original Cockroach, as he believed he was being a superhero.
* WithGreatPowerComesGreatInsanity: Memories used without a Driver madden their user, [[spoiler:and Drivers can be modified to mimic the effect of direct insertion]].
** Using a Memory without the bio-port will cause grievous bodily harm and even death with extended use, as seen with the underage high school students who shared the Bird Memory.
* {{Yandere}}: Several of the Dopants are this trope, including the T-Rex Dopant, the Violence Dopant, and the Spider Dopant.

[[folder: Characters appearing in ''Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate'']]

!! Katsumi Daido/Kamen Rider [[color:palegoldenrod:Eternal]] [[color:blue:Blue Flare]] | [-Actor: Mitsuru Matsuoka-]
Katsumi Daido is the leader of the terrorist organization NEVER, distributing the T2 Gaia Memories which resemble the Kamen Rider's Memories. With the Eternal Memory and a Lost Driver, he transforms into Kamen Rider Eternal.

* AllYourPowersCombined: Eternal can channel a 26-memory Maximum Drive with all of the T2 memories.
* BadassCape: Eternal Robe. From the setting, it can block electric shock, fire, blizzard and physical attacks, making him almost imprevious to most type of damage.
* BigBad: Of TheMovie.
* [[spoiler: CameBackWrong: According to his mother, before he died, he was actually a good person and loving son, thus why she brought him back to life to begin with. {{Subverted}}, however. He turned out okay upon resurrection. It was after his encounter with Dr. Prospect that he began to be more unhinged.]]
* CardCarryingVillain: Not afraid of proclaiming himself to be evil.
* {{Catchphrase}}: "Now, look forward to Hell." [[note]]''"Saa, jigoku o tanoshimina."''[[/note]]
* [[spoiler:DrivenToMadness: Dr. Prospect's coldblooded murder of the Quark Project subjects drove Katsumi insane.]]
* EarlyBirdCameo: A rather surprising one: SOPHIA was a guest at Anime Expo 2010 in Los Angeles, and during their last song, Eternal came on stage.
* FallenHero: As portrayed in ''W Returns: Kamen Rider Eternal'', [[spoiler:his failure to save Quarks' test subjects shocked him so much (along with Dr. Prospect's actions).]]
* FinishingMove: Five of them.
** [[color:palegoldenrod:Eternal]] 1: ''Eternal Requiem'' [[note]]An energy wave that nullifies all non-T2 Gaia memories. Can also be used as the power source for a spinning Rider Kick as portrayed in ''W Returns: Kamen Rider Eternal''.[[/note]]
** [[color:palegoldenrod:Eternal]] 2: ''Bloody Hell Blade'' [[note]]A Rider Slash using the Eternal Edge.[[/note]]
** [[color:darkgreen:Unicorn]]: An unnamed Maximum Drive where Eternal executes a Rider Punch through drill shaped energy.
** [[color:violet:Zone]]: Another unnamed Maximum Drive that brings all T2 Gaia Memories (within a certain radius) to Eternal, placing each one in a Memory Slot.
** '''T2 Gaia Memories''': ''Never Ending Hell'' [[note]]Eternal absorbs massive amounts of energy and can manipulate it to use as a finisher.[[/note]]
* KnifeNut: Eternal Edge. He also carries around a combat knife untransformed.
* [[spoiler:LaughingMad: Happens after he was driven insane by the deaths of the Quark Project subjects.]]
* MythologyGag: His design somewhat resembles that of Kiriya's Oni form from ''Series/KamenRiderHibiki'', while following the trend of white movie-exclusive Riders like [[Series/KamenRiderFaiz Psyga]], [[Series/KamenRiderHibiki Touki]] & [[Series/KamenRiderDenO Den-O Wing Form]].
** Other fans say Eternal looks a little bit like a color-swapped [[Series/KamenRiderAgito G3 Mild]], with [[TheCape a]] [[BadassCape cape]] and no [[{{BFG}} huge]] arsenal of [[MoreDakka firearms]].
* [[spoiler:NobleDemon]]: Sure, Katsumi is a ruthless fighter and killer, but [[spoiler:he saved his to-be comrades from death by turning them into NEVER, and also Mina and her Quark's comrades from despair and death, urging them to fight against Foundation X for survival. Even Shotaro and Philip mourned for him after hearing the whole story, saying that he could have become another Kamen Rider protecting Futo had he not experienced those events.]]
-->'''Katsumi''': [[spoiler: If the past is going to disappear, then at least let me have a tomorrow. That's why we're still struggling! Now, a dead person like me is still fighting for my tomorrow, how can you explain that!?]]
* PaletteSwap: Eternal Red Flare from ''W Returns: Eternal'', which is revealed to be the result of using the experimental T1 Eternal Memory. Its resonance with Daido causes it to evolve into Blue Flare before burning out entirely.
* [[spoiler:RoaringRampageOfRevenge: His reason of returning to Futo in TheMovie, against both Museum and Foundation X.]]
* [[spoiler:SelfMadeOrphan]]
* [[spoiler:UsedToBeASweetKid]]

!!All Movie Dopants

* [[spoiler:CameBackWrong: Katsumi was Maria's good son, Reika was just an escaping prisoner, Kyosui was a triad member who got betrayed (and ''without'' his CampGay trait before death), Gozo was a farmer protesting against land development, and Ken was a married SAT member.]] Subverted by a little that [[spoiler:they still retain their kind side even after becoming NEVER , but subsequent events turned them insane (though Reika was still retaining her sanity).]]
* [[spoiler:DeadAllAlong: NEVER was a project by the Museum and Foundation X reviving people to use as {{Super Soldier}}s.]]
* EvilCounterpart: To Double's own Gaia Memories. [[spoiler:Although Cyclone isn't evil.]]
* FallenHero: The group began acting as mercenaries, still holding onto their ideals. One of the effects from the serum that kept them active was the gradual vanishing of their emotions: by the time of A to Z, most -if not all- of them had already fallen to this, even if most of their personality traits were retained. [[spoiler:That and their failure to save the Quark project subjects drove them insane.]]
* PhlebotinumRebel: Villainous version. [[spoiler:Though originally this wasn't the case.]]
* SuperSoldier
* WeHaveReserves: when [[spoiler:a defeated Reika returns to Eternal]], he dismisses her and tells her that he can just make more of them.

* BloodFromTheMouth: In her death scene in the Eternal V-Cinema.

* KickChick
* MadLove: Implied towards Katsumi. The movie OST actually has a track named "Twisted Love", which plays [[spoiler:when Reika's body disintegrates after Katsumi rejects her as just a tool.]]
* NiceJobFixingItVillain: Telling Shotaro that Daido is holding Philip captive is a subtle case of this.
* MasculineGirlFeminineBoy: Masculine Girl to Kyosui's Feminine Boy.
* PlayingWithFire
* TheSmurfettePrinciple: The only female in NEVER's ranks.

!! Kyosui Izumi | [[color:gold:Luna]] Dopant | [-Actor: Genki Sudo-]
Kyosui is a man who uses the T2 [[color:gold:Luna]] Memory in order to cast illusions on his body, allowing him to bend. [[spoiler:While he manages to best Kamen Riders Double, Accel, and Joker (on separate occasions), [[EarlyBirdCameo he is defeated by]] Series/KamenRiderOOO's ''OOO Bash''.]]

* BerserkButton: According to him, being called a creepy old guy is a huge insult to [[CampGay a lady]].
* BodyguardCrush: [[spoiler:Fell in love with Katsumi before his first death.]]
* CampGay: And very open about it, to boot. He even calls himself a "lady".
* TheCastShowOff: Genki Sudo is both a mixed martial artist and a dancer, so Kyosui spends a lot of time sort of dancing in place just to show off how flexible he is.
* TheDragon: To Eternal/Katsumi Daido.
* ManlyGay: Considering the actor normally does MMA...
* MasculineGirlFeminineBoy: Feminine Boy to Reika's Masculine Girl.
* MookMaker: He is able to spawn T2 Masquerade Dopants.

* RubberMan
* TooKinkyToTorture
* VitriolicBestBuds: With Reika.
* WhipItGood
* [[spoiler:TheWorfEffect: The main reason he's defeated eventually by [[Series/KamenRiderOOO the new guy]].]]
* WouldHitAGirl: As said by himself, he's actually rougher with them.
* WrestlerInAllOfUs: [[TheCastShowOff Justified]]. Seen more in the Eternal V-Cinema.

!! Gozo Domoto | [[color:gray:Metal]] Dopant | [-Actor: Koji Nakamura-]
Gozo is a man who uses the T2 [[color:gray:Metal]] Memory to turn into the Metal Dopant, wielding a rod. [[spoiler:Defeated by Kamen Rider Joker's Rider Punch.]]

* BicepPolishingGesture: and Shotaro mocks him for it.
* TheBrute: One of two, but he is the most physically imposing member of NEVER.
* GoodThingYouCanHeal: All he needs to do to get better from a fall is to [[{{Narm}} pop the joints in]].
* MightyGlacier
* ShirtlessScene: The [[color:gray:Metal]] Memory goes into his back. ''W Returns: Eternal'' plays this one straight.
* SimpleStaff

!! Ken Ashihara | [[color:blue:Trigger]] Dopant | [-Actor: Masayuki Deai-]
Ken is a man who uses the T2 [[color:blue:Trigger]] Memory to turn into the Trigger Dopant, with a large rifle attached to his arm. [[spoiler:Defeated by Kamen Rider Accel Trial.]]

!! Seiichiro Matsui[[spoiler:/Spider Dopant]] | [-Actor: Taro Yamamoto-]

Called Matsu, he is Narumi Soukichi's friend and partner from 1999. He helps Soukichi on his cases by researching in libraries, which causes Akiko to compare him to Philip. [[spoiler: However, his jealousy of Soukichi leads him to become the Spider Dopant, eventually kidnapping Melissa with the intent of marrying her. Soukichi as Skull stops him, however, and defeats him with a Rider Kick, at the cost of Matsu's life.]]

* [[spoiler:EvilFormerFriend]]
* {{Expy}}: To Philip, minus the magical library.
* [[spoiler:LoveMakesYouCrazy]]
* MythologyGag: [[spoiler: As the Spider Dopant, he is a reference to the Spider-Man from the original series. He's even called Kumo Otoko (Spider-Man).]]

* BatOutOfHell
* MakeMeWannaShout: Allows her to control mechanical objects, for some reason.
* MsFanservice: Just check out that outfit.
* MythologyGag: Another reference to the original series, where Kamen Rider 1 fought a Bat after the Spider.
* PunnyName / MeaningfulName: While 'Komori' is written with different kanji, it's a homophone for the Japanese word meaning 'bat'.

A member of a pickpocketing ring and a thief's daughter; she saw her father killed by a certain cop [[spoiler: later revealed to be the Commander Dopant]]. Thus she treats police officers with apprehension until meeting Ryu Terui/Kamen Rider Accel. Her involvement with Ryu complicates his marriage with Akiko, yet in the end their relationship recovers and Aoi begins to reform.

* JustLikeRobinHood: Subverted in that she only really turns good after vowing to leave her life of crime.

!! Hiroshi Sagami[[spoiler:/Commander Dopant]] | [-Actor: Minoru Tanaka-]

An officer within the Futo police who saw his wife killed in front of him. [[spoiler: Thus he became the Commander Dopant, vowing to eradicate crime in the city regardless of life or cost. He eventually acquires the Gaia Memory Enhancing Adapter, increasing his power, and later abducting Akiko to attempt to convince Ryu to follow his path. Ryu decides not to, however, and defeats Sagami as Accel Booster.]]

!! Mina

A mysterious psychic who confronts Shotaro and Philip, and tells them the story of Katsumi Daido, Kamen Rider Eternal.

* [[spoiler:BackFromTheDead]]
* PsychicPowers: Manifest as...
** MindOverMatter
** PlayingWithFire

!! Doctor Prospect/Eyes Dopant

A doctor sponsored by Foundation X and leader of the Quark project, designed to augment humans with PsychicPowers.

* BigBad: Of ''W Returns: Eternal''.
* TheDreaded: The Quarks, people with amazing PsychicPowers, are absolutely ''terrified'' of him. And with good reason!
* EvilLaugh
* MorallyAmbiguousDoctorate: He's a very intelligent man, but he's also a complete maniac with no regard for human life.
* SinisterSurveillance: One of his powers as the Eyes Dopant is to implant Quarks with an "eye" that allows him to watch their every move. [[spoiler: Said eyes also can be used to kill their bearers in case of escape]].
* SuperSenses: Of the sight variety.
* WeaksauceWeakness: His creepy floating eyes can also be used to predict his opponents moves in a fight, but Katsumi gets around this by using his Eternal cape to hide his attacks from his sight. Even before that, Kamen Rider Eternal did considerably better against him, likely due to him previously using muscle movements and facial expressions to predict his movements, which he couldn't see inside the suit.
